Description of changes

Since python/cpython#97594, ast.parse can now raise SyntaxError while it would previously raise ValueError. This change was backported to 3.11.4, breaking our current test suite on Windows for Python 3.11.

Also removing UnicodeDecodeError, because it's a subclass of UnicodeError, which is a subclass of ValueError, so it is redundant.
